One pope of this name promulgated the doctrine of "the peace of Christ in the Kingdom of Christ," while another attacked the rule of the "pretended Queen of England," Elizabeth I, in Regnans in Excelsis. A later pope of this name agreed to the Concordat of 1801, which re-established relations with France. Perhaps the most prominent pope of this name attacked modernism in the (*) Syllabus of Errors and invoked papal infallibility to proclaim the doctrine of the Immaculate Conception. That pope with this name was a "prisoner of the Vatican" during Italian Reunification. The twelfth man to take this name agreed to the Reichskonkordat and is sometimes accused of being "Hitler's Pope." For 10 points, give this common name for these popes, including the longest-serving pope, the ninth.
